Abstract

The invention discloses a low-voltage circuit fault locating terminal and method used for a power distribution substation region. The fault locating terminal comprises a power distribution transformer monitoring wireless communication module, a power distribution transformer monitoring warning module, a voltage sensor, a current sensor and the like. A power circuit, a fault identifying circuit and a signal indicating circuit are arranged in a power distribution transformer monitoring collecting module. The power circuit, the fault identifying circuit and the signal indicating circuit are mutually connected, the signal indicating circuit is mutually connected with the power distribution transformer monitoring wireless communication module and the power distribution transformer monitoring warning module, a secondary-side winding of the voltage sensor is connected to the power circuit and the fault identifying circuit through signal cables, and a secondary-side winding of the current sensor is connected to the fault identifying circuit through a signal cable. The fault locating terminal can correctly judge access of short-circuit fault currents, fault region information is sent to a background system for locating through wireless communication, and therefore the locating problem of various fault circuit sections and branch circuits is solved.
